Improvement in corn-cultivators



UNITED STATES PATENT OEEICE.

IMPROVEM ENT, IN VCORN-CULTIVATORS.

' Specification forming part of Letters Patent No. 93,605, dated August10, 1869.

T0 all whom it' may concern:

Be it known that we, WILLIAM EMMoNs and DAVID A. 'WELLs, of Sandwich, inthe county of De Kalb, and in the State of Illinois, have inventedcertain new anduseful Improvements in Corn-Cultivators; and we do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of referencemarked thereon, making a part of this specication.

The nature of our invention consists in the construction of acorn-cultivator, the manner of shifting the wheels forward and back, andthe arrangement ofthe devices hereinafter set forth and described.

Figure l represents a side elevation of our cultivator. Fig. 2 is a planof the manner of attaching the frame to the axle. Fig. 3 is a View ofthe cams, levers, and rod for raising the plows.

Letter A represent-s the frame, which is supported upon the twodriving-wheels B. This frame A is composed of two parts, one of whichextends below the axle G and the other above it. The frame is pivoted tothis axle by means of the metal platesD, which allow the frame to beswung all the way around, thus moving the wheel forward or back. farenough to change it from a walking to a riding plow at pleasure.

Pivoted to the rear ends of the frame there are two bars, E, which holdup the seat.' These `bars are-supported by the rods F, which are securedto the front part of theframe, and extend backward through a ring in theupright G, and are then fastened to a hook near the back ends of thebars by a small chain.

Secured to the front part of the frame, upon each side, there is a shoe,H, to which are pivoted the plow-beams I in such manner that they can beswung freely around. Attached to each one of these beams there are twoor more plows. The handles K are fastened to these beams by means of athumbscrew, so that they can be raised or depressed at will, so as tosuit the convenience of the driver.

Extending upward from the 'rear part of the frame are the uprightstandards G, each of which has a semicircular ratchet, H, attached toits top. Running across from one standard to the other is the bar J,which has a cam, K', attached to each end, a lever,

l L, by means of which both beams I are raised at the same time, and thetwo levers M-one at each end-by means of which the beams are raisedseparately.

Attached to the rear ends of the levers M, in such a vposition that thehand can grasp them at the same time it does the handle, are the smallhand-levers N. These levers have of the main lever, attached to them,which are then secured to the dogs P. The main levers M are attached tothe beams I by means of the rod and chain R, and by means of theratchets and pawls can be secured in any desired position. By means ofthese the beams can be raised separately; but when it is desired toraise them both at once the lever L is used. The bolts or screws whichare used to secure the pawls P to the lever M are made to extend'through and form a projection on the other side. As the lever L isimmovably attached to the rod J, in raising the lever up or down the rodis turned around, which causes the cams to sweep around, and these,striking against'the projections, force the two levers downward, wherebythe two beams are drawn` upward, and are secured in position by theratchets.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

l. The combination of the frame A, axle C, and pivoted bars D D, allsubstantially as set forth.

2. The lever L, in combination With the cams or their equivalents, whenused to elevate both beams at once, substantially as specified.

3. Securing the handles to the beams by means of a thumbscrew, so thatthey can be regulated at will, substantially as set forth.

4; The levers L, M, and N, rod O, pawl P, and ratchet H, when arrangedto operate substantially as set forth.

5. In combination with the above, the beam I, bars E, chains R, frame A,metal plates D, and shoes H, when all are combined as set forth.

In testimony that we claim the foregoing we have hereunto set our handsthis 15th day of April, 1869.
